Case Name   : 创建发布且发布内容为空
Create At   : 2022/1/21
Owner       : opentestcase026
Description :
    1.两个集群均创建表
    2.创建发布订阅,无选择值
    3.修改表tb_pubsub_case001_1
    4.查询订阅端数据
    5.修改发布内容
    6.修改表数据
    7.查询订阅端数据
    8.删除发布
    9.删除订阅
Expect      :
    1.成功
    2.成功
    3.成功
    4.集群B未同步A数据
    5.成功
    6.成功
    7.tb_pubsub_case001_2同步,其余未同步
    8.成功
    9.成功
History     :
    Modified by opentestcase026 2022/5/5:增加等待5.5s,适配最新代码,并删除guc参数还
    原步骤,减少用例执行耗时
    Modified by opentestcase026 2022/6/21:订阅端新增系统表pg_subscription_rel,同步数
    据时需查询该系统表
    中同步表状态,发布端重新创建后,需要更新订阅端,该表才能更新,且数据被当做基
    础数据同步
    Modified by opentestcase004 2022/8/3:优化用例,增加数据库状态查询 & 增加基础数据
    同步功能后订阅端有基础数据的同时再在订阅端修改表数据,主键冲突,关闭基础数据
    同步
    Modified by opentestcase004 2022/8/5:setup添加断言
